Violets are often thought of as weeds in the garden, but they can also serve as ground covers. Labrador violet offers no fragrance, but it has pretty purple flowers in mid- to late spring.
Size and Method of spreading:
Labrador violet is a very low-growing plant, seldom rising higher than 4 inches. It is a colonizing ground cover. Colonizing ground covers produce underground stems that spread out horizontally and shallowly, produce roots, and then send up new shoots. These plants are strong growers and have the potential to grow aggressively.
Native geographic location and habitat:
Labrador violets are native to Canada and the north and northeastern parts of the United States.
Leaves are small (1 inch wide), heart-shaped, and a bit darker green than other species of violet. Viola var. purpurea, which is naturally occurring, has purple-tinged leaves.
The purple flowers are typical of violet plants, but a bit smaller than other species.
Fruits are small capsules and not ornamentally important.
This plant needs consistently moist soil, especially when grown in full sun. Slightly acidic soil is preferable. Since violets can grow aggressively, it is a good idea to plant them away from lawn areas.
List of pests, diseases, and tolerances:
Aphids and slugs can be a problem from time to time, but it is resistant to deer and tolerant of black walnut toxicity.
